Hi,

i have problem witch call transfer from video phone 8865 to audio only 8841 on isr 4331 and cme version 12.6.


scheme of connection:

Provider >sip trunk> Cube on g3 > sip trunk> isr 4331 witch cme.

 

when a call directly to 8865 and try to transfer with consulatation to 8841 it works fine, problem is when i try to transfer without consulatation by pressing transfer button when i hear ringback singnal.

i tried with dsp transcoding, supplementary services and many others options, but no effent.

only disabing video in voice register global helps.. but this is temoporary solution

 

always i can see:

Reason: Q.850;cause=16
